Age of Empires II quitting

I am not sure if this has anything to do with the 10.3.5 update as I haven't played in a while, but I can no longer begin a single player game. The game launches fine through classic, and after selecting a mission and watching a cutscene, the screen goes blue and then the game quits. This also happens with random maps just after they finish the loading screen. Any suggestion?
